Purpose. This describes setting-up a wave soldering system set-up for a new assembly design or checking a wave solder machine operation with a test board. Applicability. To be used for new design printed circuit assembles and during machine accept

I like what you're doing. 20 years ago anyone, hobbyists and tiny garage-shop companies could create electronics devices just as sophisticated and cool as big corporations. Today, SMT has largely trashed the creativity (and competition) that existe

Thinner: Flux thinner, NOT paint thinner We kept a spare stone in thinner in inventory. We cut PVC pipe to size, cap in one end, screw thread on the other, stone inside, filled with flux thinner and covered with a screw cap. I don't remember who we

Thank you for the reply, we will trace down the connections and double check them.

I had something similar to this on a different type of machine but it turned out to be a broken wire terminal connector at the switch causing intermittent connection. Often with safety circuits they are kept high and brought low or interrupted to dis

| We've noticed that there are many different recommendations for pad sizes for various SMT parts. This seems to vary wildly from manufacturer to manufacturer for the same case sizes. Is there any standards that can used used to specify these sizes

Is that accurate? If so, what are your aspect & area ratios? [Similar to the JerryS comment above.] * You say, � � and the average height is very high: nearly 200 pct.� => Our troop can make paste that height too. They snap the stencil-off a fast as

Hi, these are both power pins, usually connected to a dedicated inner VDD/VDDQ 1oz copper layer, making a very effective heatsink. I am guessing that not enough heat got to the ball to fully melt it, creating a weaker column rather than a beautifull

@Alexei Shkolnik Ah, I hope this doesn't become a problem. But if it does perhaps we can redesign the whole system? Push the components with a pusher that's connected from above rather than pulled by a magnet below. Perhaps the pusher can still clim

Could you make up your own adaptor cable to connect to your programmer, then fit a small form connector like a Firewire on the edge of the PCB? It should only take up about 7x7mm of real estate as opposed to a 2.54mm 5x2 pin header 12.7 x 5.08, or a
